There's much, much more to the Spanish pyrenees the the N-260 ...
Absofuckinlutely
And that there C-1311 is definitely one of them. Along with the L-511 on the opposite side of Tremp. And the L-401 the other side of Coll de Nargo. Feck all traffic & great surface on all 3 of them. Or there's the fast sweepers on the C-13 south of Cellers.
You can't really go wrong with any of the roads in that area. See leedude03's map above for a great round trip.
And then of course there's the Dolomites
So many roads so little time...
